Abstract

An automobile seat is provided that includes, but is not limited to a backrest, a seat portion, a backrest pivoting mechanism, and a two-link seat-portion pivoting mechanism. The seat portion is fastened to the backrest or the backrest pivoting mechanism so that it is pivotable about a first transverse axis and the backrest is fastened to the backrest pivoting mechanism so that it is pivotable about a second transverse axis, so that the backrest may be pivoted from a usage position in which the seat portion adopts a first position, forward about the second transverse axis into a non-usage position, in which the seat portion occupies a second position, in which the seat portion is displaced rearward with respect to the first position. The backrest pivoting mechanism is a four-link backrest pivoting mechanism, which is configured in such a manner that the second transverse axis may be displaced rearward into the non-usage position by pivoting the backrest.
